" 'Appiicafitziaivannmyze,1399. 'serial N01, 703,451. 'on man;

A .y a citizenof-theUnitedStates,residinfga-t'l'Var l having mechanism forraising theglobefforYA "ren, in the' eountyoftTrumbull and State o'f' y Ohio, have invented certain VnewA andnsefnl '.Iinprovementsin Tubular Lanterns; and'Ildo-j .declare that thelt'ollovving` is a -f ull, clearand r exact description` of the invention, which Will enable others skilledin the art 'to which it ap.- pertains to make and use the saine. l

My invention relates ,toa tubular-lantern convenience 'of lightingV the lantern, ally substantially as 'shown` and described, and` partien'larly pointed outrinthe claims.

In the accompanying-drawings, Figfnielisv `a-plan elevation of the lantern, sho'wingpa'rt of the lower portion of the globe and adjacent mechanism bro ken'awayy. ',Fig. '2 is af cross-section'online 2 2Fig. 1,' .lookingnp- Ward and'sh'owing in full and dotted'lines,

respectively, the Aposition of' the Vactuating Vmechanism when the globe isgbein g raised and lowered; Fig.' '3 is an 4enlarged cross?- section ofthe globefplat'e and the arm thereon. A representsthe k usual tubular frame, and

the globeffrainecomprises the side Wires" B v and globe-supporting plate Grand canopy'D, v, toWhich said Wires areattached. In this instance the `side Wires B are rigidgwith plate C and pivotally or loosely connected. with can- In this-class of lanterns it is both'eenven-` ient and desirableto have means for raising v lighting, and'various-means have been re.-V

and lowering thejglobe for the purpose of sorted tojby inventors 'and manufacturers having this object-in view, some engaging the top, V.suitable loops 'or keepers a lbeing usually. placed on the tubes A to confine and guide the globe-frame in its nprand down movements;

New. in order tn lift and'lowerithe globe E and :its frame together and to assure an easy `movement thereof, 'as Well as to promote a locking tendency in the mechanism at each end of the movement, I employ an elbow-lever F, pivoted on one of the tubes A and having a handle portion 2'outside and a lifting-finger 3 inside engaged with an arm ltionary portion ofthe lantern.

' 'i This arm maybeasingle piece,' as here shown,- "with` an eyeat its center to be engaged Within -thefed'geA of theeyeinjthe globesupporting w c f.

Auxiliary tothe foregoingmechanism isthe" n Wire spring H, fixed at one end et to the globe- Y plate C and` atV the otherend 5 to the arlnGr Y and servingv to promote easy movement ,bothV in lifting and lowering the globe andthe holdingof the globe in both its up andy its down. positions'.` k'For example, when lever F. has' passed its horizontal position in raising the globe the spring cornes into action to assist the lita-,and itswhole tendency thereafter is to keep the globe up.V Hence lever F does not need ltosvving past a vertical; position or to be'provided with a lockfof some 'kind tov `l keep the globe raised. So,also,when'the globe is vbeing loweredatter the horizontal positionv offlever Fv is again passed the spring Works to seat ,the globe, and its normal' action and edect is tokeep the globe dovvn;` Altogether, therefore, 4va v'spring is a very useful and desirable element in this oonneetion.

' The arxn'Ghas a downward portion g,in or Y with which the rotating lever F has .pivotal connection. .'This or any other shapeof le-K` ver kWhich-Williserve the same purposema'y be used with the arm GJ* Of course the arm' and lever Will work alone and VWithout the spring,rbut .Withnothing like as satisfactory results. c y A Manifestly either the styleof spring shown or any suitablev equivalent-thereof may be used, and it may be connected up in any Y available Way. n What I claim is.- 1f c' l.'A The tubular frame and the globe-frame', alift-lever pivoted on the tubular frame and a rigid member on the globe-frame and horif end with the said lever, substantially as described.

f 3. The tubular frame and the crank-lever thereon', in combination with the globe-frame adapted tobe raised and lowered, the rigid arm horizontally rotatable on the globe-frame and a spring connected with said arm to supplemeut the Work of the lever in raising the globe and serving as a lock, substantially as' described. y

4. The lantern-frame and the crank-lever pivoted thereofthe globe-frame having a` globe-supporting plate, a liorizontaly-rotatable arm loosely engaged o'n said plate, and a sprn g connecting said arm and plate, the said crauklever and rotatable arm being opera; tively connected, substantially as described.
